The 7500A3 by Dytran Instruments is a MEMS accelerator which features its high precision single axis variable capacitance accelerometer that has a range of about 10g. It is supported with a VC accelerometer chip that comes with a high drive for low impedance buffer and low level acceleration measurements. Plus, it is engineered to suit for frequency application having a zero to medium frequency. For different model such as 7500A3, it features a frequency response of 0 Hz and its maximum range is 1000 Hz. For this model, it is fully customized with an integrated circuit amplifier for reliable operation having a superior humidity and dirty environments.
